Ground-State Dirac Monopole
Emmi Ruokokoski, Ville Pietilä, Mikko Möttönen
We show theoretically that a monopole defect, analogous to the Dirac magnetic monopole, may exist as the ground state of a dilute spin-1 Bose-Einstein condensate. The ground-state…
Cooper pair current in the presence of flux noise
P. Solinas, M. Möttönen, J. Salmilehto +1
We study the effect of the flux noise on the Cooper pair current and pumping. We generalize the definition of the current in order to take into account the contribution induced by…
Conservation law of operator current in open quantum systems
J. Salmilehto, P. Solinas, M. Möttönen
We derive a fundamental conservation law of operator current for master equations describing reduced quantum systems. If this law is broken, the temporal integral of the current op…
Coherent superconducting quantum pump
F. Hoehne, Yu. A. Pashkin, O. V. Astafiev +3
We demonstrate non-adiabatic charge pumping utilizing a sequence of coherent oscillations between a superconducting island and two reservoirs. Our method, based on pulsed quantum s…
Measurement scheme for the Lamb shift in a superconducting circuit with broadband environment
V. Gramich, P. Solinas, M. Möttönen +2
Motivated by recent experiments on quantum mechanical charge pumping in a Cooper pair sluice, we present a measurement scheme for observing shifts of transition frequencies in two-…
Information-to-energy conversion in an electron pump
Dmitri V. Averin, Mikko Möttönen, Jukka P. Pekola
We propose and analyze a possible implementation of Maxwell's demon based on a single-electron pump. We show that measurements of the charge states of the pump and feedback control…
